I have not heard of anything new as of this point. Hopefully, they are realizing that this may not be the best coarse of action.
The 7 round limit isn't the only thing we should be worrying about. There is the 1 gun a month, insurance, waiving your hipaa rights, and a plethora of other items which are just as bad, if not worse.
Everytime i post a reply on a post like this, i make it a point to mail, fax, and email my local and state reps and advise them that i oppose any further legislation. I also call once a week as well.
If people have time to post a message, you should also make time to try and contact all of our reps here in MA. Questioning things on a forum is all fine, but voicing an opinion is better.
